At the end of June accesses to ED and admissions to hospital ward are still lower than usual.
Fear of contagion and appeals not to use ED directly by Covid-19 patients may have discouraged access also for pressing health need.

Between August 2017 and April 2019, 55 patients comprising the following three disease groups were enrolled Sjogren's syndrome 39 patients; postradiotherapy sialoadenitis ten patients; and post-RAI sialoadenitis six patients. Quantitative salivary scintigraphy was recorded, and a formulated questionnaire including the Summated Xerostomia Inventory was utilized to assess acute/chronic symptoms. All patients received at least three serial salivary gland ductal irrigations with a one-month interval in our outpatient department.
The general response rates for each disease groups are as follows Sjogren's syndrome 61.5% (24/39); postradiotherapy 60% (6/10); and post-RAI 83.3% (5/6). Among the patients with Sjogren's syndrome, the parotid scintigraphic Tshowed a significant positive correlation with the responsiveness of salivary irrigation (P = 0.046), whereas the treatment tended to be irresponsive in patients who previously took medicine for their related discomfort (P = 0.009). In the postradiotherapy and post-RAI groups, no significant factors were found to be associated with the responsiveness of irrigation.
Simple salivary ductal irrigation without complex equipment can be performed as an outpatient procedure to alleviate glandular swelling or xerostomia in patients with Sjogren's syndrome, postradiotherapy sialoadenitis or post-RAI sialoadenitis, and it can be considered an alternative management approach for patients refractory to conventional strategies.

However, existing aqueous zinc-ion batteries usually suffer from poor cyclability and cannot operate at subzero temperatures. Herein, to solve these problems, the electrolyte in aqueous zinc-ion batterie is optimized by adding the appropriate amounts of diethyl ether and ethylene glycol. Results show that the addition of 1% diethyl ether contributes to the best cyclability at 25 °C. Furthermore, the addition of 30% ethylene glycol results in the best electrochemical performances at 0 and - 10 °C. This significant performance improvement at low temperatures is ascribed to the high ionic conductivity of the modified electrolyte and the low charge transfer impedance of the battery with the modified electrolyte at 0 and -10 °C. It is also shown that the modified electrolyte can decrease the nucleation overpotential of zinc plating, enhance the interfacial stability between the zinc metal and electrolyte, suppress the zinc dendritic growth and side reactions, and decrease the self-corrosion rate of the zinc anode. This work offers a facile strategy to realize aqueous zinc-ion batteries with excellent cyclability and antifreezing ability and may inspire research on other aqueous energy storage systems.While dynamics of particles in slurries is usually evaluated by dynamic light scattering measurements, this technique had only been applicable to particles in the bulk slurries. Because this limitation is mainly owing to strong reflection of light, the dynamics of particles in slurries spreading/drying on solid substrates is to be obtained by spatially separating the reflection light from scattering (signal) light. This may allow us to track the particles in practical samples such as cosmetics or inks spreading on solid surfaces.
We developed novel "dark-field dynamic light scattering microscopy". The system was evaluated with test samples of polystyrene beads dispersed in several viscosities of bulk glycerol aqueous solutions. This setup was then applied to slurries spreading/drying on planar and nonplanar substrates.
The results for planar surface indicate that origin of coffee-ring are the particles flowing into the edge of the droplet just before complete drying. On a skin-modelled nonplanar substrate, the slurry on bumps was found to maintain semi-dry condition longer than that at dents. This suggests that the dispersive medium was supplied to bumps from dents. This unique flow was explained as effective drying from the bumps increased surface tension at the bumps to pull up the liquid around.

Interaction of various ionic species present in the novel low salinity surfactant nanofluids with scCO/COsaturated aqueous phase interface and at the interface of COsaturated aqueous phase/mixed wet (with COand Decane) limestone surface at the conditions of low salinity at reservoir conditions are to yet to be understood.
This study, carried out for the first time in low salinity at scCOloading conditions at 20MPa pressure and 343K temperature, comprises of wettability study of the limestone surface by aqueous phase contact angle measurements using ZrOnanoparticles (in the concentration range of 100-2000mg/L) and 0.82mM Hexadecyltrimethylammonium bromide (CTAB) surfactant. Molecular dynamics simulations results were used to understand the underlying mechanism of wettability alteration and interfacial tension (IFT) change.
